4.17.1 Antenna Radiation and Efficiency
Typical MGM220P radiation patterns and efficiency for the on-board chip antenna under optimal operating conditions are plotted in the
figures that follow. Antenna gain and radiation patterns have a strong dependence on the size and shape of the application PCB the
module is mounted on, as well as on the proximity of any mechanical design to the antenna.
